HYDRAULIC MINING-MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 273,397, dated March 6,1883.

Application filed March 24,1882. (No model.)

To all whom it may concern:

draulic Mining Apparatus; and I do hereby declare the followingdescription and accompanying drawings are sufficient to enable anyperson skilled in the art or science to which it mostly appertains tomake and use my said invention without further invention or experiment.

In the drawings, Figure 1 shows alongitudinal section of my device; Fig.2, a cross-section on line no 00.

My invention relates to an improved construction and arrangement of thatclass of hydraulic pipes and nozzles which are used for directing anddelivering a stream of water against a bank in hydraulic mining.

My improvement consists in sucha construction of the pipe that thenozzle can have both a vertical and horizontal play through the mediumof two moving water-tight joints for the purpose of directing a columnof water to any desired point of the compass, and'at the same timethrowing an incessant stream of water from the nozzle, such constructionto be substantially that hereinafter described.

Arepresentsa section of pipe through which water is forced by its ownpressure when conducted from higher points. I), an iron band, isinserted on the inside of the pipe between which band and the inside ofthe pipe a circu lar leather flapisinserted. Both band and flap are heldfirmly to the pipe by means of setscrews passing through the side of thepipe leather and band.

,.B represents a pipe-elbow, as much smaller in diameter as thethickness of the band 0, through which band the pipe B plays.

(11 is an iron hand firmly riveted to the extreme end of and outside ofelbow B.

c is an iron band inserted on the inside of section A and outside ofsection B. The band 0 is fastened to the end of sectionA by screws. Theband d plays between band 0 and the flap, the flap passing between theedges of bands 0 and d, and also lying flat on the inside of the edge ofthrough which band g the pipe 0 plays.

section B, the leather flap being pressed watertight by the passingforce of the water, thus making a swivel of the three bands parallel toeach other, one of which bands revolves between the other two, and thepressure of the water makes the two bands 01 and 0 also watertight.

'0 represents another section of a pipe-elbow, as much-smaller indiameter as the band 9, The bandf is fastened at the end of sectionC,and plays between bands 9 and e, a leather flap being arranged afterthe manner of the other elbow union at b 0 cl.

I is a fastening passing half-way around the pipe, and to be securelybolted to planking or a log.

K is a socket wherein to insert the end ot'a lever for the'pnrpose ofturning the pipe 0 in any desired direction. The diaphragm L passes thelength of the pipe 0 to prevent a circular motion of the water.

1 am aware that expensive hydraulic machines have heretofore been madechiefly of cast-iron with central bolts and knuckle-joints, which resistand waste the force of the passing water. My machine avoids suchobstacles.

Havingthus described my invention, what I claim, and wish to secure byLetters Patent,

1. The combination of the section of pipe A with elbow-sections B and G,united by a joint constructed with metallic bands, and a flap of leatheror other flexible material, arranged to render water-tight the seam ofthe bands with the pipe, and also the seams between the bands,substantially as above shown and described.

2. The combination, with the ends of pipesections, of bands forming aswivel or revoluble joint and leather or other flexible flap, renderin gwater-tight both the seams between the pipe and the bands and thosebetween the bands themselves, substantially as herein shown anddescribed. 7
